How to make an internet clock with NTP, Pi Zero W and RasPiO InsPiRing

I’ve been messing about with the Pi Zero W and one of my RasPiO InsPiRing boards to make a colourful clock that keeps accurate time using NTP (Network Time Protocol). Because the Zero W has WiFi onboard, it’s perfect for things like this. It’s quite a visual thing, so I made a video about it… Here’s the Code If you want a walk-through of the code, I made a little walk-through video of it, but decided to keep that separate because not everybody would want that level of detail. You can find that after the […more…]

Media Kit - RasPiO Inspiring

Any photo on this page can be clicked for the full-size version. Alex Eames from RasPi.TV is running a KickStarter campaign for RasPiO Inspiring – a new system of RGB LED boards using APA102c LEDs. The Kickstarter campaign can be found here… https://rasp.io/inspiring The idea behind the system is that the shapes can fit together in a modular way to make whatever shape you want – either 2D or 3D. There’s a straight-8 stick, a triangle, a circle, a semi-circle and a square, but also a small pHAT-sized driver board for Raspberry Pi. The semi-circle […more…]

RasPiO InsPiring - a new system of RGB LED boards controllable by Pi and just about anything

I’ve been playing with RGB LEDs on and off over the last year or so. They’re amazing things. It’s incredible to me that something so small can produce such bright and brilliantly coloured light. I’ve played with the Adafruit DotStar Pi Painter project (using APA102), which is enormous fun. Also the Pimoroni MOTE (also APA102), which makes everything plug-and-play. Then there was the McRoboface from 4Tronix (using 2 sizes of WS2812). Then back in October 2016 I bought 4 quadrants of 15 WS2812 on ebay to make a 60-element clock. And then one day, amidst […more…]

RasPiO Portsplus Picademy - NEW product.

If you’ve been hanging around the RasPi.TV blog for a while you’ll have heard of the RasPiO Portsplus board. It’s a little PCB with the Pi’s GPIO port numbers on that you can use to avoid counting pins when wiring up your GPIO projects. A few months ago I was visiting Pi Towers. Ben Nuttall mentioned that they use the Portsplus at Picademy, but sometimes people put them on the wrong way up and it causes confusion. The original Portsplus has GPIO port numbers one one side and pin numbers on the other side. It […more…]

RasPiO GPIO Zero Ruler

You may remember this time last year I KickStarted a 6-inch ruler with the most important RPi.GPIO code on it. I’ve been using it myself an awful lot in the last year when coding. So it won’t surprise you to learn that I’m now doing another one for GPIO Zero. Since GPIO Zero is about the easiest way imaginable to get into Python GPIO tinkering, I think this will be really helpful for people. I’ve already been using the prototypes and find them an extremely helpful reference. Here’s what it looks like… It’s twice as […more…]

RasPiO Analog Zero - an 8-channel zero-sized board for Raspberry Pi

Exciting news today. I’ve just launched a new KickStarter project for a Pi Zero sized analog board. I’ve called it the RasPiO Analog Zero. It works with GPIO Zero and is very easy to use. Here’s what it looks like… …and here’s the KickStarter video showing some of the things you could use it for… If you like the look of it, please come and back us on KickStarter.

Central Heating Furnace Monitoring and Control with RasPiO Duino and Raspberry Pi

We went to Poland for the Easter holiday. When we got there the house was really cold (6°C), having been vacant for several months. We’ve got a fairly substantial solid-fuel furnace in the basement and a large room full of coal to burn. We have a gas boiler too, but we want to get rid of the coal to repurpose the space it occupies. Burning it is the most logical solution, but it involves some work. But I’ve tried to make it a bit more fun. The furnace is an interesting beast. It’s taken me […more…]

Using MCP3008 to measure temperature with GPIO Zero and RasPiO Pro Hat

In the previous article I showed you the GPIO Zero Experimenter’s Kit I put together to go with the RasPiO® Pro Hat. Today I’m going to give a quick overview of how to use the MCP3008 analogue to digital converter to read the TMP-36 temperature sensor. This gives us a temperature reading (in °C) that we can use to make “decisions” in our Python program. In our case, we’re going to switch on a red LED when the temperature is 24 °C or greater. But there are all sorts of other things you could do, […more…]

GPIO Zero Experimenter's Kit and RasPiO Pro Hat

On Tuesday I had a funny thing happen. I was testing an analogue to digital converter (ADC) chip – the MCP3008 – to see how well it worked on the RasPiO® Pro Hat. I had it all wired up, and powered up the Pi, typed a few lines of GPIO Zero code, and… It worked, but not quite how I thought it should. Instead of giving a value of 1.0 for 3V3 and 0 for 0V it was giving 0.67 for 3V3. I left it running and went for lunch. During lunch the ‘lights went […more…]

RasPiO Pro Hat - Putting Pi Ports in Perfect Positions for Productive Play

Today I launched the RasPiO Pro Hat on Kickstarter. It’s a Raspberry Pi Hat for GPIO tinkering (it goes perfectly with GPIO Zero). It arranges the GPIO ports in numerical order around a mini-breadboard, which, to my knowledge, has not been done before. It also replaces the RasPiO Breakout Pro (now end of life) because it protects all the ports from over-current and over/under-voltage as well. It should prove a very useful board for GPIO tinkering and education. Have a look at the video and pop on over to the RasPiO Pro Hat campaign page […more…]
